Driven by the “Internet of Everything” (IoE) vision, the demand for smart materials is growing. Wood, one of the most abundant and renewable resources, has long been a staple in construction and furnishing applications. To further expand its application range, this study developed a high-strength, stable wood-based triboelectric material through a synergistic biphasic mechanism. The in situ growth of flame retardants and the formation of a dense char layer significantly enhanced the fire resistance of the wood-based triboelectric material, reducing the heat release rate (HRR) by 95.4% and total heat release (THR) by 94.2%. The dense laminate structure provided an excellent impact toughness (126 kJ m^–2). As a smart sensor, the wood-based triboelectric material demonstrated the ability to recognize human motion states and trajectories, exhibiting great potential for applications in smart homes. This study provides valuable insights for exploring the potential applications of wood as a smart material.

通过双相阻挡实现坚固稳定的木质摩擦电材料


在“万物互联”（IoE） 愿景的推动下，对智能材料的需求正在增长。木材是最丰富和可再生的资源之一，长期以来一直是建筑和家具应用的主食。为了进一步扩大其应用范围，本研究通过协同双相机制开发了一种高强度、稳定的木质摩擦电材料。阻燃剂的原位生长和致密炭层的形成显著提高了木质摩擦电材料的耐火性，热释放率 （HRR） 降低了 95.4%，总热释放 （THR） 降低了 94.2%。致密的层压结构提供了出色的冲击韧性 （126 kJ m^–2）。作为智能传感器，这种木质摩擦电材料展示了识别人体运动状态和轨迹的能力，在智能家居中显示出巨大的应用潜力。本研究为探索木材作为智能材料的潜在应用提供了有价值的见解。
